Who but Will.i.am could get Mick Jagger to rap – yes, rap – over a glitzy Ibiza beat in 2011? Who else would even think of such a wonderfully batshit idea? On the first single from his forthcoming solo LP #willpower, the Black Eyed Peas mastermind strews dodgy rhymes ("I woke up in the morning/Hard like morning wood in the morning") over diamond-bright synths, while J. Lo handles the efficient hook. It all feels a bit perfunctory – except for Mick's guest verse, a kitschy delight delivered in a "Midnight Rambler" snarl.

While watching a Budweiser commercial during the Super Bowl, Sir Mix-a-Lot thought the skinny female models in the ad didn’t represent reality. So he wrote this ode to ample bottoms, featuring its famous to-the-point lyric: “I like big butts and I cannot lie.” MTV banished the video, featuring shaking booties and sexually suggestive fruit, to 9 p.m. or later. “I thought my career was over,” he told Rolling Stone. “Then I called Rick Rubin, and I told him the video was banned, and he was like, 'Great!' We sold another 2 million records.”
